The cement considered here is blast-furnace slag cement composed of Portland clincker and ground granulated blast-furnace slag (GGBFS). Two different cements were tested: CEM III/B 32.5 (65 to 80% GGBFS and 35 to 20% Portland clincker) and CEM III/C 32.5 (80 to 95% GGBFS and 20 to 5% Portland clincker).
The slag cement was used for a high-rise building's foundation in Indianapolis. On this project, Irving Materials Inc. incorporated the slag cement with its concrete mix. In total, 1,700 tons of ...
